摘　　要：依据对北大红楼的工程地质调查,其地基条件为不均匀地基土,借助FLAC^(2D)有限差分程序分析不均匀地基对北大红楼变形破坏的影响,发现北大红楼上部建筑出现的宏观变形破坏特征与下部地基岩土层性质、厚度、空间分布状况等密切相关。分析结果对于北大红楼维修加固设计具有重要的指导意义。The subgrade foundation soils is uneven according to the geological investigation of Red Building of Peking University. The characteristic of macroscopical deformation is relative with the property, thickness, distribution, etc of the subgrade foundation soils, through FLAC2D which is a two-dimensional finite-difference program. The result of analysis have a important significance when maintaining and repairing the Red Building of Peking University.
